Here is a recording done during the fireworks of san juan at the beachof barcelona, spain. I was standing in front of the mapfre building, between the building and the sea to be exact. Fireworks were being launched behind me from the beach and their sound was reflected off of the building in front of me. The effect you hear are thereflections of the building. The building is shaped to visually reflect the city back onto the beach. Hence each floor has mirrors in a 45 angle downwards, all around the building (look it up on google for details). The sound must be coming from different points each located further away, creating a kind of discrete doppler effect, i suppose, although i am not yet 100% sure what exactly causes this. I am holding the microphone sideways, so you hear the explosions on your right ear and the reflection traveling to the left. In reality, you hear the explosion behind you and the reflection traveling up along the building. If you are ever in barcelona end of june during "san juan", you should check this out!. Recording done with my zoom h2n and its internal microphones. Hope you enjoy.
